To ILZZ whom it may concern:

Be it known that we, M. HENRY LANE and REUBEN W. Mnvnnw, citizens of theUnited States, residing at Kalamazoo, county of Kalamazoo, State ofMicl. 'gan, have invented new and useful Improvements in Vehicle Circle-]?lates, of which the following is a specification.

Our invention consists in certain improved features of construction toincrease the strength, appearance, and utility of such devices.

In the drawings forming apart of this specification, Figure l is aperspective view of that portion of the device which is connected withthe forward vehicle-axle; Fig. 2, the part connected with the forwardbolster when in use; and Fig. 3, afront elevation of these, parts asconnected when in use, with a partbroken away on the section-line 2 2 inthe other figures.

The axle plate P is provided with the usual confining-bars, (1,66, andclip 0, except in this instance they are made half-round and hollow onthe inside, forming a casing to the confining-bolts c, which are locatedon the front and rear sides of the axle B. v The heads of the bolts carelocated in the countersunk holes S of the plate P. The lower ends of thebolts 0 pass through the clip 0, and are secured by nuts a. With thepintle F the brace which connects with the reach is to be connected.(Not here shown.) A nut is to be placed on the threaded end of thepintle F.

c and making the bars a a to serve as sheaths to said bolts, danger ofbreaking is obviated, and the construction has a more finishedappearance, and, if desired, softer, more brittle, or cheaper materialmay be used.

The upper plate, D, when in use is to the under side of thevehicle-bolster. The hole bis located over the center axis, 1. Inthehole in said axis the king-bolt is to be located. The two end and thecenter bearing portions of the bolster-plate D are extended allintegrally connected by a bar,

vice, and greatly strengthens the parts, especially bracing the centralextension, with the end a of which the usual front brace (thesame beingan upward extension of the reach-brace) is connected when in use.

Other well'known features of construction hereshown are deemed to besufiiciently understood without further description.

Having thus described our invention, what we claim as new, and desire tosecure by Let' ters Patent, is-

The combination, with a vehicle-axle, of a circleplaie provided with thehollow sheathbars, and-securing-bolts located in the hollows thereof,substantially as set forth.

In testimony of the foregoing we have hereunto subscribed our names inthe presence of two witnesses.
